The United Nations confirms that the past eight years have been the hottest on record

The past eight years have been the hottest on record, confirmed this Thursday (12). World Meteorological Organization (World Meteorological Organization (WMO)) despite the persistence of the phenomenon no ninawhich temporarily mitigate the effects of global warming.

Six major international data compiled by the World Meteorological Organization point to the same reasons: “Ever-increasing concentrations of greenhouse gases and accumulated heat,” highlights the UN organization in a note confirming the conclusions of the European Program on Climate Change. Copernicuswhich were published this week, and those of US Meteorological Agency (NOAA) and NASA, also released on Thursday.

In 2022, the world’s average temperature will be close 1.15 °C above Pre-industrial levels, according to the World Meteorological Organization.

Last year was the eighth year in a row that annual global temperatures were at least one degree above observed levels. Between 1850 and 1900.

For the past eight years, it has been The hottest year was 2016followed by 2019 And 2020.

Temporary effect
the Paris agreement on Climate, which concluded in 2015, urged that global warming be reduced to 1.5 °Cwhich, according to scientists, would make it possible to reduce the effects of climate change.

But the World Meteorological Organization warned Thursday that “the possibility of exceeding the 1.5C threshold – temporarily – increases over time”.

Thanks to the La Niña meteorological phenomenon, which tends to lower the temperature of the oceans and which has been going on since 2020, the warming has been somewhat contained.

This phenomenon can continue until March, according to the World Meteorological Organization, and it will follow after a neutral period, characterized by the absence of the La Niña phenomenon and its opposite, El Nino.

The UN agency highlighted that the impact of La Niña, on the planet as a whole, would be “short-term” and “will not reverse the long-term warming trend caused by record levels of greenhouse gases that trap heat in our atmosphere”.

In 2022, several regions will set record temperatures: the polar regions, as well as vast sectors of the Earth Middle eastAnd ChinaAnd Central Asia and North Africa.

Meanwhile, Europe recorded the second hottest year on record: SpainAnd FranceAnd United Kingdom and Italy exceeded their average temperature records, according to the Copernicus program.

Disasters
In 2022, the Director of the World Meteorological Organization, in a note, denounced “many catastrophic meteorological disasters that have caused many casualties, destroyed livelihoods and undermined access and infrastructure for health, food, energy and water,” Petrie Talas.

The leader recalled the deadly floods that submerged a third of the waters of the Nile Pakistan He warned of a “humanitarian catastrophe” in Horn of Africaa victim of drought for several seasons.

WMO also identified drier-than-normal conditions in Patagonia, South America, and southwestern North America.

“Since the 1980s, every decade has been warmer than the last” The average temperature in the decade was between 2013-2022 1.14 degrees Celsius Above pre-industrial reference, vs 1.09 °C Between 2011 and 2020, estimated Intergovernmental Panel on Climate Change (IPCCabbreviated in English).

In the face of increasingly extreme meteorological events, Taalas insisted it was necessary to “strengthen preparedness”.

In this regard, the Secretary-General of the United Nations said, Antonio Guterresannounced in COP27 plan More than 3 billion dollars In order to cover the world with early warning systems by 2027.

Currently, only half of the 193 member states have these types of systems.
